Kirchner Block & Brick’s products take center stage in Alton Riverfront and Marina District Master Plan in Alton, Ill.
By Mary Hediger
While concert-goers enjoyed the inaugural Big Gig live music festival this past Fall, and many of them admired the beautiful new Alton Riverfront Amphitheater where the event was held, most of the music lovers weren’t aware of the balance and harmony of materials utilized in the creation of this magnificent outdoor venue located in scenic Alton, Ill.
St. Louis-based Kirchner Block & Brick and their VERSA-LOK® weathered retaining wall units and Romanstone® Olympia concrete pavers played a starring role in this extensive municipal project. The new Amphitheater, part of the Alton Riverfront and Marina District Master Plan recently completed for the City of Alton, is the centerpiece of the ambitious renewal of the Alton riverfront vicinity of this historic town on the Mississippi River.
This stunning redevelopment project was lead by a team of construction and design companies who worked hand in hand with the city leadership, including Phil Roggio, director of development and housing, design and construction.
The revitalization and redevelopment of the Riverfront and Marina District has enabled Alton to return to its historic, 19th century river town heritage and provide significant boosts in economic development and tourism for the 21st century. These efforts focused on the planning and design of a master plan, as well as the design of multiple facilities, including a 300-slip marina, an excursion boat mooring, a river-walk promenade, the Amphitheater, a public fountain plaza, pavilions, parks, pedestrian walkways and a pedestrian bridge connection to the historic downtown area.
The overall planning and design of the district, plus the eventual implementation and construction, has resulted in more than $30 million in public and private redevelopment on the riverfront.
The project design team and construction oversight was lead by Dan Bockert of Planning Design Studio, who is the company’s principal and also served as the project manager. The company was assisted by EWR Associates, architects; Sheppard, Morgan and Schwaab, Inc., civil engineers; Horner & Shifrin, electrical engineers; Forsyth Engineering, structural engineers, and Hydro Dramatics, fountain design. The general contractor was RCS Construction, Incorporated. The Alton, Illinois City Parks department, headed by Executive Director Brad Cunningham and Assistant Executive Director Rhonda Lewis, is responsible for the Amphitheater operations.
Material choices make the difference
According to Planning Design Studio’s Bockert, Kirchner’s VERSA-LOK and Romanstone product lines made a major difference in the aesthetics of the overall project vision. “The range of material color and texture choices offered by Kirchner Block & Brick’s product lines helped us to coordinate finishes between colored concrete, precast material and poured in place concrete,” he said.
Kirchner Block & Brick – a division of Midwest Products Group – is a manufacturer and distributor of masonry and landscape/hardscape products, and the company sells these products throughout the Midwest via independent dealer/distributors. In addition to the VERSA-LOK Retaining Wall Systems and the Romanstone Interlocking Paving Stone products used in the Alton Riverfront Amphitheater project, the company’s other key product lines include Keystone® Retaining Wall Systems, Cultured Stone®, Trenwythe and Boral® Brick.
The cost of the total riverfront renovation project was approximately $4.4 million. Bockert credits Kirchner with keeping the material costs low while providing a beautiful finished product. “Kirchner Block & Brick helped the design team develop cost alternatives for plaza paving that ultimately brought the project in at budget.”
Roggio added: “The City of Alton is extremely pleased with the products provided by Kirchner. The retaining walls and pavers utilized at the amphitheater lend themselves to the superior aesthetic design we sought for this project.”
“The Alton Riverfront Amphitheater project is proof positive that all entities involved in large public and private construction and renovation projects – including planners, municipalities, owners as well as designers – can find ways to create beautiful, enduring, cost-effective hardscape projects without sacrificing quality or compromising design,” said Mark Wilhelms, CSI/CDT and Kirchner Block & Brick’s sales manager.
Alton Riverfront and Marina District
The Alton Riverfront and Marina District Master Plan designated the central portion of the site for an open space, multi-use public park and common area, including an outdoor amphitheater. This property is part of the City of Alton, Easton Commons.
The finished Amphitheater is located in the central portion of Easton Commons. It was designed by Planning Design Studio to be seen as part of the overall open space concept, and centers on a circular fountain geyser and a concentric circle of pedestrian-friendly, smaller vertical fountains. This central fountain area consists of a series of decorative paved areas and grassy open space. The paving was created in contrasting color and texture to depict the theme of “the meeting of the great rivers,” graphically illustrating the plan view of the Mississippi River from the confluence with the Illinois River through the Missouri River Confluence to the St. Louis Riverfront.
It’s all in the Amphitheater
The Amphitheater, with a total seating capacity of 4,000 for organized events, includes 600 wall bench-type seats. A six-foot section of turf is between each row. There is an additional acre of sloped grassy area behind the fixed seating area. The grassy portion of the amphitheater is intended for blanket-type seating. Moreover, for certain events, the overall design allows for additional grassy seating behind the stage and around the fountain for a theater-in-the round effect. For informal or seating in the round, seating capacity can be doubled.
Kirchner supplied its VERSA-LOK weathered retaining wall units for the amphitheater seating and the handicap-accessible ramps. Planning Design Studio’s Bockert noted, “The seating walls and precast coping blends the line and shape of the amphitheater’s formal geometry to the natural open space of the surrounding riverfront landscape.”
According to Sheppard, Morgan & Schwaab, Inc. Principal Charles Sheppard, P.E., “The VERSA-LOK weathered mosaic retaining wall units were selected for the low seating walls and handicap ramp walls because of their natural look, versatility, and ease of construction considering the varying elevations of the amphitheater bowl.”
The plaza area pavement was constructed using Romanstone Olympia concrete pavers. The plaza paving is used symbolically to represent the Alton street grid in the area around the fountain, and the fountain represents the geographic location of Alton along the Mississippi River when viewed from above the plaza. The varied modular paver units radiate from the “center” fountain, which represents the city, with the rest of the plaza paving symbolizing the region.
